ARMATURE FOR DYNAMO-ELECTRIC MACHINES.

SPECIFICATION forming part of Letters Patent No. 567,746, dated September 15, 1896.

Application filed April 11, l 89 6.

1'0 all whom it may concern:

Be it known that we, FREDERICK J. IIAERER and CHARLES L. GIKELEITER, citizens of the United gtates, residing in the cit-y and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Armature-Magnets, which improvement is fully set forth in the following specification and accompanying drawings.

Our invention relates to armature-magnets; and it consists of novel means for supporting the coils thereof, whereby in the case of accident to any portion of said coils or windings, as a wire burning out or becoming broken from any cause, the disablement of the machine for a long period is avoided, provision being made for readily detaching that portion of the armature containing the coil or winding in which the broken Wire is located and for readily inserting a new one in its place, whereby any stoppage of the machine for a considerable time is avoided.

It also consists of a novel construction and assemblage of troughs or similar devices around which the windings are made.

It also consists of a novel construction of clamping devices for holding the different coils or windings in position.

It further consists of novel details of construction, all as will be hereinafter set forth.

Figure 1 represents an end view of an armature-magnet embodying our invention. Fig. 2 represents a perspective View of a portion of one of the troughs employed with the coils or windings removed, the same being shown in detached position. Fig. 3 represents a transverse section through the hub of the head seen in Fig. 4:. Fig. 4 represents a perspective view of one of the heads employed in detached position and a clamp adapted to be mounted thereupon. Fig. 5 represents a longitudinal section on line y y, Fig. 1. Fig. 6 represents a transverse section on line a: 00, Fig. 5. 7

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, Adesignates an armature, the same consisting of the heads 13, which are provided with the hubs Qwhich have therein the threaded holes or sockets D,

$erial No. 587,15 '7. (N0 model.)

said heads being mounted upon and caused to revolve in unison with the shaft E by means of keys or similar devices.

F designates notches in said heads B, in

which are adapted to rest the limbs or members G of the inverted supporting-troughs 1-1, the same being preferably made of channeliron, and said limbs G having the connecting member or top J.

K designates a trough which may be a suitable length of channel-iron having the base L, and is adapted to rest upon the top J of the trough H, said members J and L being separated by the insulation R, and said trough K being provided with the upwardly-extendeach other in the manner indicated in Figs.

1 and 6 and beingheld together by means of the rivets V or other similar devices.

In Fig. 2 is shown a perspective View of the supporting-trough H and the outer trough K,

mounted thereupon, the other troughs being removed.

V designates shoulders near the extremities of the limbs Gr, adjacent the termination of themembers M of the trough K, the base L of the upper trough being cut out to the extent indicated at IV in Fig. 2, which point also marks the termination of the top J of the trough I-I, said members L and J being cut out, as indicated, in order to furnish room for the coils or windings X, the relative position of which to the troughs being indicated in Figs. 5 and 6.

Y designates a clamp employed, the same consisting of the upright triangular-shaped body portion Z, which has its sides recessed at A for the reception of the ends of the members G, as indicated in Fig. 1. B designates the foot of said member Z, which is deflected laterally and is adapted to be held upon the hub G by means of tap-bolts G or other similar devices, it being understood that the number of clamps Y correspond to the number of notches F and also to the number of threaded sockets D. O designates the top of said clamp Y, said top having the depend- [co ing sides I), while the body portion Z is provided with the elongated slot E, through which the bolt F is adapted to pass, said bolt engaging a suitable portion of the head B, whereupon it will be seen that the clamp Y is positively and effectively held in the desired position.

The operation is as follows: The troughs II, K, N, I, and Q are assembled in the manner indicated in Figs. 1 and 6, the abutting surfaces of said members being separated by the insulations R, S, T, and U, and said troughs being held in position by the rivets V or other devices. The wire X is then wound about the troughs in the manner indicated in Figs. 5 and 6, so that the spaces between said troughs are filled with the coils or windings. The supporting-troughs II are then placed in position, as indicated in Figs. 1 and 5, it beingnoticcd that when the troughs are in assembled position the two abutting members G will fill a notch F, as indicated in the upper portion of Fig. 1, and thus all the coils or windings will be locked and prevented from axial movement when the same are all assembled. The clamps Y are next placed in position, the same being initially held by means of the bolt F, after which they are tightened in position by means of the bolt G, the ends of the members G interlocking with the recesses A and the edge of the top 0 abutting against the ends of the troughs M, N, P, and Q, respectively, as will be understood from Fig. 5. It will thus be seen from the foregoing that in case of accident to any coil or winding, as a wire burning out or becoming broken from any cause, upon ascertaining in which winding the accident has occurred, which can be readily done, the removal of the proper clamp Y, which holds the damaged coil in position, will enable the entire coil composed of one set of the troughs built up and held in position in the manner described, as seen in Fig. 6, to be lifted from the supporting-head B and another coil or winding to be readily placed in position, thus necessitating the stoppage of the machine for but a comparatively brief interval compared with the time which would ordinarily be required to rewind the whole armature, it being of course understood that a number of the removable coils seen in Figs. 5 and 6 are to be kept on hand in case of accident.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. An armature, having a plurality of coils or windings, heads upon which the same are supported, clamps mounted upon said heads and adapted to lock said coils in position and means for securin said clamps to said heads, substantially as described.

2. An armature, having a plurality of coils or windings, heads upon which the same are supported, clamps mounted upon said heads and provided with overhanging tops and recessed sides adapted to lock said coils in posi tion and means for securing said clamps to said heads, substantially as described.

3. An armature consisting of an inverted trough, a trough supported thereupon, a plurality of troughs of decreasing cross-sectional area supported on said last-mentioned trough, suitable insulation therebetwecn, a plurality of windin located in said troughs, heads upon which the latter are supported, clamps for locking said windings in position and means for securing said clamps to said heads, substantially as described.

4. In a device of the character described, a plurality of heads, notches in said heads, upon which a series of coils or windings are adapted to be supported, hubs attached to said heads, and clamps adapted to hold said coils in position, said clamps being provided with feet adapted to be secured to said hubs, substantially as described.
